ACCELEROMETER Russian patent published in 1996 - IPC

FIELD: instrumentation engineering. SUBSTANCE: accelerometer has pendulum suspended from two restoring elements in base ring. The latter together with pendulum is set between two magnetic circuits which simultaneously accomplish function of immobile cover of angle sensor of capacitive type. Magnetic circuits are installed with clearance relative to pendulum with the aid of protrusions. Mobile covers are applied on pendulum. Magnets and pole pieces are put on magnetic circuits. Coils of power sensor are mounted on pendulum. Thermally sensitive coils are placed on magnetic circuits. Package composed of magnetic systems and pendulum with restoring suspension is set in ring and is gripped by lock ring forming sensitive element of accelerometer. Sensitive element is located in case which carries adjustment coil, additional coil and amplitude amplifier-discriminator. Network of thermally sensitive soils and adjustment coil connected in series is electrically linked in parallel to network of thermally sensitive coils and additional coil connected in series. Their electric parameters are selected depending on definite relation. EFFECT: improved functional reliability and sensitivity. 3 dwg
